需要为以下功能传递CGFont
CGFontCreateCopyWithVariations(<#font: CGFont!#>, <#variations: CFDictionary!#>))
最佳答案
这是一个小例子:
var font = UIFont.systemFontOfSize(15.0)
var fontName = font.fontName as NSString
var cgFont = CGFontCreateWithFontName(fontName);
var copiedFont = CGFontCreateCopyWithVariations(cgFont, nil)
